HAND TRACTOR.

Application filed January 25, 1921. Serial No. 439,755.

To (IN/'1!) from may concern Be it known that I, \VILLIAM ll.Fmnrnnsnonn, a citizen of Australia, residing at Hayward, in the countyof rilaineda and State of California, have invented certain new anduseful Improvements in Hand Tractors, of which the following is aspecification.

My invention is a tractor hand plow the plow handles of which arepivoted 'to be turned horizontally out of the way so that the plow mayturn sharp corners, particularly those which are fenced in.

Referring to the annexed drawings in which my invention is illustratedand which form a part of this specification,

Figure 1 is a side elevation of a tractor hand plow embodying myinvention.

Figure 2 is a transverse vertical section of the plow taken on line 2-2of Figure 1.

Figure 3 is a longitudinal section of the tractor engine andtransmission taken on line 3-3 of Figure 2.

Figure 4t is a horizontal section taken on line 4c-4c of Figure 1showing the pivot mounting of the plow handles.

Figure is a vertical section taken on line 5-5 of Figure 4.

In the drawings 1 indicates a horizontal frame on the forward end ofwhich is mounted a transverse stationary hollow shaft 2. A sleeve isjournaled on the shaft 2. A gas engine 4t is mounted on the shaft 2 andsleeve the engine casing having formed thereon sleeves 5 and 6 whichrespectively surround said shaft and sleeve 3, the sleeve 5 beingsecured to the shaft and the sleeve 3 turning in the sleeve (3. Theengine casing includes a hood, 7 integral with and between the sleeves.3 and 6, within which hood a worm gear 8 is secured on the inner end ofthe sleeve 3, and through the lower end of said hood a shaft 9 extendslongitudinally of the plow, on which shaft is secured a Worm 10 in meshwith worm gear the shaft 9 being journaled in bearings 11 and 12 on theengine casing in the frontand rear of hood 7. A crank disk 13 is securedon the rear end of shaft 9 within the engine crank case 141 which isintegral with the rear end of hearing 12. The engine cylinder 15 ismounted on the crank :ase 14- in which cylinder reciprocates the piston16 and the piston rod 1'? is connected to the crank disk 13. Forwardlyof the hood 7 is mounted a fan 18'including a casing 19 and a fan wheel20, said casing being formed on the forward end of the bearing 11 andsaid fan wheel being secured on the shaft 9 within said casing. From thefan casing 19 extends an air nozzle 21 to the forward side of the enginecylinder cooling fins 22. A traction wheel 25 is journaled on the shaft2 by means of its hubs 26 and 27, the hub 26 being journaled on theshaft and the hub 27 being secured on the sleeve From the hub 26 projectspokes 28 which support a rim 29 From the hub 27 project spokes 30 whichsupport a rim 31. ()n the rim 29 are bearings 32 and on the rim 31 arebearings 33. A plurality of transverse shafts 3 1 are respectivelyjournaled at one end in bearings 32 and at the other end in oppositebearings 33. ()n one end of the shafts 34: are cranks to which areconnected the outer end of rods 36 which project radially from an eccentric ring 37 surrounding an eccentric 88 secured to one end of shaft2. On the shafts 3st are secured grousers 39 which are caused toapproach the ground in a horizontal position by the eccentric 38, ring37, rods 36 and cranks A plow blade 10 is swivelly mounted on the rearof the frame 1, said blade being secured to the lower end of a rod llwhich is swiveled at its upper end in a bearing 42 secured to the underside of said frame. A gasoline tankt3 is mounted on the rear of theframe 1 above the frame, a tube 4H leading from said tank through thehollow shaft 2 and connecting to the engine carburetor.

Upon the rear of the frame 1 a circular plate is secured by means ofscrews 51 on which plate is formed an upstanding hollow journal 52. Aring 53 surrounds the journal 52 and turns thereon,v and from oppositesides of said ring arms 54 extend rearwardly and upwardly at an angle,to which arms are' secured the lower end of plow handles 55 which may beturned to the right or left with the ring 53 on the journal 52. Un therear half of the periphery of plate 50 is an upstanding flange 56, inthe upper edge of which are notches 5'1", 58 and 59, the notch 57 beingin the center of the flange or midway between its ends and the notches58 and 59 being at the rightand left of the notch 57 respectively. AU-shaped latch frame 60 is pivoted at its ends at 61 to the inside ofarms 5% and a latch 62' is secured to the intermediate member of. saidframe. 61

for engaging the notches 5T, 58 or 59. A chain 63 is secured at itslower end to the rear end of latch 62 and at its upper end to the upperpart oi. the plow handles 55.

\Vhen the latch 62 engages notch 57 it holds the plow handles straightor longitudinally with relation to the implement, and when the latchengages the notches 58 or 59 it holds the plow handles turned to theright or left.

\Vhen the implement comes to a corner the operator pulls the chain 63which disengages the latch 62 from notch 57, and then turns the handles55 to the right or left according to the way the implement is going andthen releases the chain so that the latch engages a notch 58 or 5.) andholds the handles turned to the right or left so that the implement mayturn a sharp corner. lVhen the corner is turned the operator pulls thechain 63 and releases the latch from the notch 58 or 59 and then turnsthe handles back straight and releases the chain and allows the latch todrop back into notch 57 and hold the handles straight.

Having described my invention, I claim:

1. In a tractor hand plow, a journal on the rear of the implement, aring turnable on said journal, plow handles secured to said ring, anarcuate flange on the rear of the implement provided with notches, and alatch for engaging said notches to lock the plow handles againstswinging movement.

2. In a tractor hand plow, a journal on the rear of the implement, aring turnable on said journal, plow handles secured to said ring, anarcuate flange on t-he'rear of the implement provided with notches, alatch for engaging said notches to lock the plow handlesagz'linstswinging movement, and a chain connected to said latch and the plowhandles for withdrawing said latch from said notches.

In testimony whereof I aifix my signature.
